To solve an exponential equation, take the log of both sides, and solve for the variable. Example 1: Solve for x in the equation . Ln(80) is the exact answer and x=4.38202663467 is an approximate answer because we have rounded the value of Ln(80).. Check: Check your answer in the original equation.
Answer: x =10
Step-by-step explanation:
I'm sorry if its not right
The area of the square pyramid is 105 sq inches.
Step-by-step explanation:
Given,
The base of the pyramid (b) = 5 inches
The height (h) = 8 inches
To find the area of the square pyramid.
Formula
The area of the square pyramid = 2bh + 
Now,
The area of the square pyramid = 2×5×8 +
sq inch
= 105 sq inches
Hence,
The area of the square pyramid is 105 sq inches.
Answer:
X= -1
Step-by-step explanation:
So to solve equations like this, you want to isolate the variable first. Then you begin to simplify by dividing each side of the equation by a factor that does not contain a variable.
Answer:
49/4
Step-by-step explanation:
x² -7x +(7/2)²=(x-7/2)²
x²-2x·7/2+ (7/2)²=(x²-7/2)²
(7/2)²=49/4
